. a machine' providedwith a gitudinally serrated, headed Wire nails, bradsionthelike from l'en 'ths of Wire the object. in providing ,on such nails being to increase: the external grippingsuriace of the nail or the like, and 1 25 to increase tlierigidity of its shank Without enlarging the diameter-o1 the original stock from which it' is made. The;machineoperm tions take place insucha manner that, Whilst the nail or'other blanks are :being cnt 0E,

of anail or the like are carried on simultaneously and continuously, thereby ensuring a verylarge outputiof finished nails or other articles from the machine. 7

An important feature 01" the machine is that the head and also the point of each nail formed by it are absolutely concentrically located in relation to the axis of the sha-nlr" from which it is formed, and'any bends in during the serrating operation. a p

Above the tableau is provided a multiplewvire-cropper Z2 into 8 which is fed by any k-nown ire feed--1neoha+ nism', a" number of Wires 5 from which blanks 5 are cropped ofi and fall into hop per 0 Where] they are transversely stacked Atthe bottom of the said hopper 0 a ribbed 7 sliding-ishitt-plate dis agitated-bya cam 6Z through a forkechrocking-lever d gtliese movements induce the ribbed-sliding-shiftplate at toteed through a slot 0 into a chan-' nel tube 0 a continuous transversely ar ranged stream of blanks 5 which? are 'a-rrested in their progress by a fiexi bly-mounted" spacing-feed-drum or roller f with grooves in its periphery f which regu lates their rate of delivery into a-chute'f provided to convey thenibetweenarota-tabl y mounted and transversely milled-drum h milled counterq ressure-block awna may be composed ot platesg, as showziin'glfig are 7 of the drawings, and whilst this occurs, by the provision on both the revolving-milled-drum it and the counter-pressure block 7 of flanges 71, and 9 arranged at the desired angle on one or both sides thereof, the point 22/ of the product a (Fig. 9) or the like is formed: at the same time, by the provision of a high-speed reciprocating heading-plate m, heads 12 of the product a are formed, or by providing flanges [L1 or alternately reciprocating heading-plates m on both sides of the milled-drum it both ends of a blank on may have points 11?, or heads n as desired. The whole combination of mechanical movements are coupled together by means of suitable gearing consisting of a toothed wheel, 70, a pinion Z61 on a crank-shaft carrying a fly-wheel 0 and chains or belts p of the known type and are driven in the usual way.

The milled-drum 71 is provided with fine teeth 7& on or around its periphery and it may be made in one solid piece, or built up in laminar form from plates,'rings or segments h, as shown in Fig. 6. for the purpose of enabling nails n", or the like of different lengths to be made. The serrations 72, serve to rotate the nail blank 11 or the like duringits heading and pointing.

After passing under the spacing drum supported by springs f the blanks n, stubs or the like are brought between the periphery of the revolving milled drum it and the corresponding and co-operating concentrically milled face 9 and flange g of the counter-pressure-block g. Said milled counter-pressure-block g is mounted in guides g and held against the blanks n by means of a spring g acting through toggle levers or their equivalents. To suit the different diameters of wire employed for making nails or other articles it is necessary to provide in each case countor-pressurebloeks 9 whose actingface-curvature corresponds to a true concentric line relative to the axis of the milled drum it when wire is being operated upon between it and the periphery of said u'iilled-drum it. As the milled-drum 7L revolves, it rolls the nail blanks n or the like across the milled-face g of the counterpressure-block g causing the blanks a or the like to revolve at a great speed and at the same time it serrates them, as shown at of. lVhen blanks or the like a are made into nails a? by this rolling process, one end of each blank a may be brought between pointing devices consisting of cutters, rollers, or the like, but preferably and as before described one edge of the milled-drum 7i and the corresponding edge of the counter-pressure-block g are fashioned into tapered flanges 72/ and g to form the point 12 which is thereby rolled out on the spinning blank. Simultaneously with the rolling-out of the point the vibrator-plate or header m, op-

erated by pneumatic, hydraulic or mechanical means, not shown, is caused to operate upon the other or opposite ends of said spinning blanks n, and by its blows form that part of the spinning blank n which protrudes beyond the bevelled, curved or plain hczul-torming edges of the milled-drum it and counter-pressureblock into a spun and beaten head a (-oncent ric with the ;-hank thereof. The face of the vibrator-plate 1/1 is curved or set a an angle m from the plane of the head-forming faces of the milled-drum 72 and the Ct)tllll'(l'-]li'tfif lll'flblock t] in a. manner that the depth ol. the

blow vill be less as the blank 17 lirst enters it, and increasing as shown in Figure 5 of the drawings to full depth as the head 11 is formed thereon.

After the heading of the blanks has been completed. nails, brads, pins or the like roll down a delivery chute Z and drop into a receptacle j ready to be packed.

The milled-drum 71, may in conjunction with its counter-pressuire-block g, be so milled that they are capable of producing on the nail blank n or any other article passed between them, annular ridges and grooves, knurling, spirally-formed or any pattern. figured or otherwise.

The wear of the working parts is reduced to a mininnnn, as the greater part of the operating surfaces are rotating on the coinparatively soft material from which nails, or the like are formed, and these take the wear.

The machine may be provided with a double-pointing n'iilledrevolving-dri1m and its concomitants as shown in Figure 8 of the drawings.

It will be obvious that, by heating the wire, rod or the like before it is passed through the machine or by interpo ing a heating or re-heating chamber of the known kind between the spacing-feed-drum f and the milled-drum 72/ and countor-pressure block g. heated blanks '7? or the like can be fed and hot-rolled in their more ductile ron dition and into forms not possible in their cold state without departing from the spirit of the invention.
